Industrial Heater Elements

Careful consideration of watt density is necessary in the design of industrial heating elements. Described as the wattage per unit of the heated surface area, watt density is typically identified in watts per square inch (W/in2) or watts per centimeters squared (W/cm2). There is much variation in the range of watt density, and each electric heating element has its own individual watt density characteristics.

Watt density is a determining factor in the ability of a heater to disperse heat from the resistance element to the heater sheath and finally on to the process. Excessive watt density can lead to such problems as failure of the heater, damage to the material or substance being heated, or damage to other components. To ensure optimal heater performance and longevity of the element, watt density should be matched with consideration to substance type, flow rate, and temperature, in addition to other dynamics particular to the application.
